These are rooftop or outdoor-mounted systems ideal for medium to large commercial buildings, such as shopping complexes and hospitals. They contain all components in one unit, including fans, compressor, evaporator, and condenser. These units are easier to install than water-cooled units and don’t require a cooling tower but may be less efficient in extremely hot climates.

Key Features:

• No cooling tower required

• Easy to maintain

• Good for buildings with roof space

• Lower installation cost than water-cooled units
